We determined the mineral nutrients and toxic elements (Ca, Cu, Fe, Mg, Zn, Cd, Cr, Mn, Ni, and Pb) in five types of coffee by atomic absorption spectrometry and inductively coupled plasma mass spectrometry. The decomposition of the samples took place in a microwave digestion system with HNO<sub>3</sub> and H<sub>2</sub>O<sub>2</sub> reagents. Partial validation of the method was performed by using the certified reference material (NCS ZC 73014). Univariate and multivariate statistical methods were used to compare both the coffee samples and the techniques used. No significant differences were found between two used methods. Significant differences occurred between the coffee samples but only the application of multivariate statistics helps to distinguish among samples from different locations.

Abstract A rapid procedure, based on closed vessels microwave digestion and inductively coupled plasma-mass spectrometry (ICP-MS), was evaluated to ascertain the effect of chronic exposure to cadmium on intracellular accumulation of minor and essential trace elements in cultured epithelial cells (Caco-2 TC7). For all measurements, the method of external calibration was used and 3 elements (Be, Sc, In) were selected as internal standards. Optimization procedures are discussed and results are presented for the total determination of 9 key analytes (Na, Mg, Ca, Cr, Mn, Cu, Zn, Mo, and Cd) in certified reference materials (CRMs) and 20 samples of Caco-2 TC7 cells long-term exposed to Cd. The performance characteristics of the analytical system were evaluated by calibration and linearity, limits of detection and quantitation, accuracy with spiking, trueness and repeatability with available CRMs. As a complement to the ICP-MS determinations, both available CRMs and cell samples were analyzed either by electro thermal-or flame atomic absorption spectrometry. The results were in good agreement with the ICP-MS results.

Major, minor and trace elements in wines from Greece were determined by inductively coupled plasma–mass spectrometry (ICP–MS). The concentrations of 44 elements (Na, Mg, P, K, Ca, Cu, Co, Cr, Zn, Sn, Fe, Mn, Li, Be, B, V, Sr, Ba, Al, Ag, Ni, As, Sn, Hg, Pb, Sb, Cd, Ti, Ga, Zr, Nb, Pd, Te, La, Sm, Ho, Tm, Yb, W, Os, Au, Tl, Th, U) in 90 white and red wines from six different regions in Greece for two consecutive vinification years, 2017 and 2018, were determined. Results for the elements aforementioned were evaluated by multivariate statistical methods, such as discriminant analysis and cluster analysis, and the wines were discriminated according to wine variety and geographical origin. Due to the specific choice of the analytes for multivariate statistical investigation, a prediction rate by cross-validation of 98% could be achieved. The aim of this study was not only to reveal specific relationships between the wine samples or between the chemical variables in order to classify the wines from different regions and varieties according to their elemental profile (wine authentication), but also to observe the annual fluctuation in the mineral content of the studied wine samples.

Abstract This study was designed to determine the 11 metal elements (Al, Cr, Mn, Fe, As, Ni, Cu, Zn, Cd, Sb, and Pb) in soy sauce and their migration from the containing glass bottles. Inductively coupled plasma mass spectrometry (ICP-MS) was applied for the determination of the elements and one-factor-at-a-time method was employed for optimizing the ICP-MS parameters in migration experiment and microwave digestion experiment. The developed method was successfully applied to determine the content of 11 elements. The results showed that the experiment had excellent correlation and sensitivity. The accuracy of the elements in the migration study and test of soy sauce itself ranging from 84.25% to 118.75% was satisfied, and the precision of the method was validated and the RSD was no more than 15.5%. The concentration of all the detected metal elements migrated from the glass bottles were between 0.3450 and 2.398 ng·mL−1, and the risk assessment indicated that the metal elements in soy sauce had no risk to the public health. The proposed methodology in this study was successfully applied for the quality control for metal elements in soy sauce and the containing glass bottles for the first time, and a research method suitable for soy sauce consumption process control and risk assessment has been established.

Abstract A method validation of the total analysis of cadmium (Cd), lead (Pb), arsenic (As), and mercury (Hg) in foodstuffs by inductively coupled plasma/mass spectrometry (ICP/MS) after closed vessel microwave digestion is presented. Due to the lack of reference method for ICP/MS techniques in food and, based on the project of the European Committee of Normalization (CEN/TC 275/WG 10), the Agence Française de Normalisation (AFNOR) guidelines NF V03–110 were used for the evaluation of this method based on 2 steps, sample preparation and multielement detection. Several criteria considered as compulsory (linearity, specificity, precision under repeatability conditions, and trueness) have been estimated and discussed, in addition to intermediate precision reproducibility, the limit of detection, and the limit of quantification. Furthermore, a comparison with in-house methods using electrothermal atomic absorption was performed using an external proficiency testing scheme and food samples. The results indicated that this method could be used in the laboratory for the routine determination of these 4 cumulative toxic metals in foodstuffs with acceptable analytical performance.

Literary Origins

The aim of the study was to investigate the possibility of using а concentration of aluminum as a marker of neurodegenerative diseases.Material and methods. To achieve this goal, there was carried out an analysis of literary origins from various databases, in particular Scopus and PubMed.Results. The analysis shows that by now there has been accumulated strong evidence that certain neurodegenerative diseases are associated with chronic exposure to low-dose of aluminum: in particular, Alzheimer's disease (AD); motor neuron disease or amyotrophic lateral sclerosis (ALS); multiple sclerosis (MS) and a number of others.Conclusion. Thus, it can be assumed that the measurement of the concentration of Al in the blood plasma will make it possible to identify a group people with of high risk of AD, which will allow starting preventive treatment at the earliest stage of the disease. The capabilities of the existing methods of analysis: atomic absorption spectrometry with electrothermal atomization (GFAAS) and inductively coupled plasma mass spectrometry (ICP-MS) enable to solve this problem.

In this work, the determination of low contents (less than 0,0005 wt. %) of arsenic in complex alloyed samples of nickel alloys was carried out by means of inductively coupled plasma mass spectrometry (ICP-MS) and atomic absorption spectrometry with electrothermal atomization. Also, the ICP-MS method was used to determine the arsenic content in chromium, which is an alloying component of nickel alloys. A technique for dissolving a sample and preparing it for analysis is presented. Spectral interferences are eliminated by applying mathematical correction equations, a reaction-collision cell and using corrective additives. The correctness of the results obtained is confirmed by the analysis of certified reference materials of nickel alloys and chromium.
